Most alleles are either present or absent, which gives two choices. Those which are not, say for skin color of mixed-race heritage, can exhibit a large number of possibilities, and though the exact count might be difficult to determine, it is of course finite.

How many alleles do your gametes have?
Gametes should contain one allele for each gene locus. This means that gametes will have one allele for each of the genes on the chromosomes they are carrying. It is estimated that humans have about 20,000-30,000 genes - meaning each gamete would therefore have 20,000-30,000 alleles.
How does polygenic trait differ from simple inheritance?
Well polygenetic inheritiance are traits that is controlled by multiple genes, so for one trait you may have more than two gene controlling it, human eye is an example. For polygenetic inheritance you cannot do a pedigree and calculated the percentage. For mendelian inheritance it all about two alleles for one trait where one is definetly more dominant over the other, it is much simpler than the polygenic trait and can be calculated through a pedigree.
How many copies of a gene does each somatic cell have?
One. A gamete is a haploid cell containing one copy of each chromosome (23 in humans). Each chromosome contains one copy of each gene. Therefore, a gamete contains one copy of each gene.
How many alleles does an offspring inherit?
912
What is an example of allele?
an allele is an alternative form of a gene that governs a characteristic, like hair or eye color. an individual gets 1 allele for each charecteristic from each parent. There are dominant alleles and recessive alleles. The dominant allele is the allele that is the person's physical appearance, and the recessive allele is the one that isn't visible but the person has in his/her genotype.
About how many genes do horses have?
An individual Thoroughbred cannot have more than two different alleles for each gene locus, one on each chromosome. How many alleles are available at a certain gene locus is variable based on what the gene controls and how many alleles are available and their frequency in the population.
What is the name given to genes that have more than two alleles?
Polymorphic locus or polymorphic gene. Many geneticists use the term locus (plr. loci) for a gene (i.e. section of a chromosome)
What id genetic variation?
Genetic Variation is a measure of the genetic differences there are within populations or species. For example, a population with many different alleles at a locus may be said to have a lot of genetic variation at that locus. Genetic variation is essential for natural selection to operate since natural selection can only increase or decrease frequency of alleles already in the population
How many alleles do your gametes have?
Gametes should contain one allele for each gene locus. This means that gametes will have one allele for each of the genes on the chromosomes they are carrying. It is estimated that humans have about 20,000-30,000 genes - meaning each gamete would therefore have 20,000-30,000 alleles.

What are some examples of allele's?
Multiple alleles means that for a specific locus on a chromosome there can be 3 or more forms of that gene (allele). Only one allele can be inherited because they are found on homologous chromosomes. Height is not a multiple allele because it is associated with many genes on several chromosomes (plus environmental factors) so this would be polygenic inheritance. Multiple allele trait is the ABO group. The allele for A B or O (3 alleles ) is found on the same locus, therefore only one of them could be inherited EXAMPLE: DNA
How many different outcomes can you have when you have 10 alleles?
There is not enough information to answer this questions. 10 alleles in 1 loci? 10 alleles total? 10 alleles for that gene in the population?
How many copies of alleles do organisms carry?
It depends on the organism but humans have two alleles.
How many copies of a gene does each somatic cell have?
One. A gamete is a haploid cell containing one copy of each chromosome (23 in humans). Each chromosome contains one copy of each gene. Therefore, a gamete contains one copy of each gene.
How many alleles for a trait are there?
2
How many years do locus come out?
every 2 years and 4 months
Does a single pair of alleles always determine an individual trait?
No, often many other alleles will also determine the same trait. For example, many alleles put together will determine a person's skin color.
